SMTP Email Setup and Troubleshooting

No thoughts?

I'm using CPANEL and CI 3.x.

Depending on what I put in the config, and how I enact the config.. the two prominent errors are:
'Failed to send AUTH LOGIN'
'Unable to send email using PHP SMTP'

Note, if I change the protocol to mail or sendmail, debugger shows it successfully sends.. but I still never the email.

Very frustrating.

Latest Code:

PHP Code:

                                       $config = array(
                                            'protocol' => 'sendmail', // smtp, mail, sendmail
                                            'smtp_host' => 'mail.somedomain.com',
                                            'smtp_port' => 25,
                                            'smtp_user' => '[email protected]',
                                            'smtp_pass' => '*****',
                                            'mailtype'  => 'text',
                                            'charset'   => 'iso-8859-1',
                                            'crlf' => "\r\n",
                                            'smtp_keepalive' => TRUE,
                                            // 'smtp_crypto' => 'tls',
                                            // 'newline' => "\\r\\n",
                                            'wordrap' => TRUE
                                        );
                                        $this->load->library('email', $config);
                                        $this->email->set_newline("\r\n");

                                        $this->email->from('[email protected]', 'title');
                                        $this->email->to($vEmail);
                                        $this->email->subject('blah blah blah');
                                        $this->email->message('Testing the email class.');

                                        $vEresult = $this->email->send(FALSE);
                                        echo $this->email->print_debugger();
